DiCaprio Boards Nolans Inception

Leonardo DiCaprio has signed on to star in Inception, the first post-Dark Knight film for director Christopher Nolan.

The contemporary story is described as taking place within “the architecture of the mind.”

Nolan set up the project less than a month ago at Warner Bros., the studio where he made his Batman films as well as the thriller “Insomnia.” The filmmaker and the studio are aiming for a 2010 release.
